A cellular phone paging system that uses a frame oriented scheme to transmit and receive mobile unit pages with reduced delay is disclosed. Each mobile unit in the cellular phone network is assigned a paging slot within the frames on the forward control channel. If a plurality of pages are to be sent along the forward control channel and the pages are assigned to the same paging slot, the pages will be transmitted in successive paging slots beginning with the assigned slot rather than in the assigned slot in a series of sequential frames. In order to receive its pages, a mobile unit inspects its assigned paging slot and the next sequential paging slots if its assigned paging slot has been filled with a page request to another unit. The mobile unit continues to check sequential paging slots until it identifies a page to itself or identifies an empty slot. The mobile unit may reduce its power consumption by turning off some of its electronic circuitry while not monitoring the contents of its assigned slot and, if necessary, the contents of successive slots. In this manner, paging delays between base stations and mobile units are reduced to a minimum while maintaining idle mode power consumption conservation provided by frame-based paging schemes.
For use in a wireless telephone network including a call processing system operative to communicate with mobile units on a forward control channel by transmitting control signals in a series of concatenated frames having a plurality of paging slots, each of said paging slots having a corresponding plurality of mobile units assigned thereto, a method of transmitting pages to a mobile unit, comprising:
For use in a wireless telephone network including a call processing system operative to communicate with mobile units on a forward control channel by transmitting control signals in a series of concatenated frames having a plurality of paging slots, each of said paging slots having a corresponding plurality of mobile units assigned thereto, an improved system for transmitting a page to a mobile unit, comprising:
A method of receiving a page by a mobile unit in a cellular phone network using a call processing system, the call processing system communicating with the mobile unit by transmitting control signals on a forward control channel in a series of concatenated frames in accordance with a frame oriented scheme, each frame including a plurality of paging slots that are available or unavailable, each of the paging slots having a plurality of mobile units assigned thereto, wherein a mobile unit has an assigned paging slot, and said mobile unit has an ON mode during which it can receive control signals and into which it is placed when the assigned slot is transmitted on said forward control channel, the method comprising the steps of:
An apparatus for receiving a page, the apparatus integrated into a mobile unit, wherein the mobile unit operates within a cellular phone network using a call processing system, the call processing system communicating with the mobile unit by transmitting control signals on a forward control channel in a series of concatenated frames in accordance with a frame oriented scheme, each frame including a plurality of paging slots that are available or unavailable, each of the paging slots having a plurality of mobile units assigned thereto, wherein the mobile unit has an assigned paging slot, and the mobile unit has an ON mode for monitoring the forward control channel for control signals during a time period in which its assigned paging is being transmitted, the apparatus comprising:
